This is the October 1923 issue of the American and English trade journal "Typewriter Topics" (Vol. 55, No. 2). It was published as "The 50th Anniversary Historical Number" to mark the 50th anniversary of the typewriter industry (not of the magazine itself) and consists largely of a long anonymous article entitled "A Condensed History of the Writing Machine: The Romance of Earlier Effort and the Realities of Present Day Accomplishments." The item reprinted here is the original 1923 magazine (in a scan of an old photocopy of it). It is 194 pages, which probably includes almost all of the magazine.

Much of this material was reprinted later under three different titles. It is useful to distinguish them from this original version:

The long "Condensed History of the Writing Machine" article was reprinted in book form in 1923 as "The Typewriter: History & Encyclopedia." (NY and London: Business Equipment Publishing Co., 1923). 114 pp.

The 1923 book-format version was reprinted again in 1981 under the title "Collector's Guide to Antique Typewriters." (Arcadia, CA: Post-Era Books, 1981.) ISBN: 911160-86-8. 125pp + index. Post's reprint contained an additional Foreword and also numerous advertisements reprinted from other contemporary magazines (that is, the reprinted ads in it are not those of this original "Typewriter Topics" October 1923 number).

The 1923 book-format version was reprinted again in 2000 by Dover Publications under the title The Typewriter: An Illustrated History. ISBN-10: 0-486-1237-7. 128pp.
